Despite this, studies of OCs in ringed seal blubber at Holman Island and in sea birds at Prince Leopold Island in Lancaster Sound show declining concentrations of PCBs and DDT-related compounds from the 1970s to 1980s then a levelling off during the 1980s and early 1990s. Many of the temporal trend data for contaminants in Canadian Arctic biota are confounded by changes in analytical methodology, as well as by variability due to age/size, or to dietary and population shifts. Contaminant measurements in bearded seal, harbour seal, bowhead whale and killer whale tissues from the Canadian Arctic are very limited or non-existent. Studies on contaminants in walrus are limited to Foxe Basin and northern Québec stocks, while migratory harp seals have only been studied recently at one location. All major beluga, ringed seal and polar bear stocks along with several major sea bird colonies have been sampled and analysed for OC and heavy metal contaminants. The geographic coverage of information on contaminants such as persistent organochlorines (OCs) (PCBs, DDT- and chlordane-related compounds, hexachlorocyclohexanes, toxaphene) and heavy metals (mercury, selenium, cadmium, lead) in tissues of marine mammal and sea birds is relatively complete.
This paper reviews the current state of knowledge of contaminants in marine biota in the Canadian Arctic and where possible, discusses biological effects.
Its mission is to empower businesses to Reclaim Waste™ by focusing on the conversion of organic wastes, such as manure, digestate, and food and beverage manufacturing wastewaters, into clean water, concentrated co-products, and when possible, renewable energy.Recent studies have added substantially to our knowledge of spatial and temporal trends of persistent organic pollutants and heavy metals in the Canadian Arctic marine ecosystem.

With new projects starting in 2020, Digested Organics expects to be filtering over 1,000,000 gallons per day of manure by the end of next year. The company has 10 systems operating across five states for livestock farms, food and beverage manufacturers, and industrial producers.
“We will use this prize money to continue our mission of delivering value-added solutions to hard working farmers who are tasked with the increasingly difficult job of producing our food and caring for our land in a time of climate change.”įounded in 2013 by Robert Levine, Ph.D., and Ian Charles, Ph.D., Digested Organics is a leader in filtering and treating high solids wastewaters and process streams to help customers reduce wastewater disposal costs, reclaim clean water for reuse, and produce valuable co-products. “Our team has been delivering advanced solutions for manure management to farmers for over five years and it is an honor to receive this recognition,” said Robert Levine, Chief Executive Officer at Digested Organics.
The Challenge recognizes leadership in solving the economic and environmental challenges facing livestock farmers in the 21st century: “A future where there is less waste means a future where farms are more productive and our ecosystems are healthier.” The company received $50,000 in non-dilutive funding and recognition as the leading waste-to-value solution for livestock producers. Farmington Hills, MI, J-( PR.com)- Digested Organics is pleased to announce that it has won the inaugural Manure Challenge, sponsored by The Yield Lab Institute, Cargill, The Maschhoffs and WeWork Food Labs.
